4.Application led April 10, 1925` Serial No. 22,030;

. of the present invention is to produce an improved wire fabric for beds, couches, and the like, the parts of which are so Aformed and arranged that the fabric possesses the required flexibility.- in all directions, does not sag when-the superimposed weight is removed, can be readily folded longitudinally and transversely, if that is desired, and can be manufactured at a saving in cost of production and of material. To the accomplishment of Athis object the yinvem tion. consists in the improved wire fabric hereinafter described and particularly pointed out in the appended clalms. i

The preferred form of the invention is illustrated in the accompanying drawings in which:

Fig. 1 is a plan of a bed or couch bottom employing the improved wire fabric;

Fig. 2 is' an enlarged perspective view of .one ofthe main links of the fabric;

Fig. 3 is a view similar to Fig. 2 of one of the auxiliary side links;

Fig. 4 is a detail of one form of coupling link; and

Fig. 5 is a similarl view of another form of couplingdink. l l I In the illustrated embodiment of the invention, the improved wire fabric is shown attached to avbed or couch frame of which the longitudinal side members are indicated at 7 and the end pieces at '8. The wire fabric 'comprises a series" of lateral rows of main links 9 which are held in cooperative relationship by means of the intermediate or coupling links 1.0. Each main link-9 consists of a strand of wire bent upon itself, as shown in Fig. 2, with its two side or limb sections 1l and 12 extending parallel with each other, the inner ends of the limbs being connected by the curved transverse member 13. By bending the transverse member 13 inward with respect to the side links 11 and 12, the pockets or notchesV 14 are formed, and these pockets are adapted to receive and hold in place the hook portions 15 of the coupling links 10. The free ends 17 of the limbs 11 and 12 are bent under to form long, relatively flat hooks.

The hooks 17 of the first lateral row of links are adapted to engage the series of end pieces 8 of the bed or. couch frame. The hooks 17 'of the remaining rowsoflinks are adapted to engage the loop portions 19 of the coupling` links 10. The last row 20 of coupling links 10 are adapted to engage the series of helical springs 21 connected with ghe other end piece 8 `of the bed or couch rame.

When the main links 9 and intermediate or coupling links 10 are assembled together to constitute the improved wire fabric shown in Fig. 1the limbs 11 of each 'longitudinal row of links are arranged relatively helical springs 18 connected with one of the f close to and substantially parallel with the j limbs 12 of the adjacent longitudinal row of links. This mode of arrangement provides a series of longitudinall extending linksections each composed o two closely positioned limbs, although the limbs of the individual links are spaced relatively far apart. The proper lateral spacing between the limb 11 of 4one link 9 and the limb 12 of the adjacent link 9 is secured b hooks 17 lof each individual link 9 slightly outwardly, as shown clearly in Fig. l2, and by spacing the hook portions 15 of the coupling links 10 accordingly. The divergent or angular directions of the sides of `the hooks 17 of each individual link 9 result in a convergent relationship of the hooks of the adjacent links when the latter are arranged side by side, as shown in Fig. 1. This convergence of the hooks 17 of the limbs 11 and 12 of adjacent links not only serves to aid in properly spacing and holding apart the limbs of the adjacent'lnks, but

`also affords the hooks a better purchase or hold in the loops of the helical springs 18 and in the loops 19 of the coupling links 10.

The coupling links 10 are so shaped as to cooperate with the limbs 11 and 12 of the adjacent longitudinal rows' of links 9 .to form substantially continuous lineal bending the.

los

lmetal, and partly because with this form of coupling link the sides thereof are more nearly in a straight line with the sides or limbs of the main links 9.

rll"he angular distance between the hooks 15 of the coupling links will depend upon the desired spacing between the limbs 11A and 12 of adjacent links 9. One hook 15 of a link 10 is adapted to be received in a pocket 14 of a link 9 and the other hook 15 of the link 10 is adapted to be received in the nearer pocket 14 of the adjacent link 9.. Ylhe loops 19 of each row of cupling links (except the last) receive the converging hooks 17 of adjacent links 9. The loops 19 of the last row of coupling links receive the hooked inner ends of the helical springs 21. The convex middle portion of each transverse member or piece 13 connecting the limbs 11 and 12 together, serves to keep the hooks 15 in the pockets 14 and to return them* thereto when displaced therefrom.

By constructing and arranging the parts of a wire fabric as described above, the separate transverse links or strands of wires heretofore commonly used to connect the longitudinal links together are eliminated, the curved transverse members 13 of the longitudinal links serving in cooperation with the coupling links 10 to absorb the lateral stresses imposed upon the fabric..

The present arrangement'makes for a strong, durable, and inextensible structure.

ln order to provide the side edges oit the fabric with double strands of wire, and at the same time have as smooth a side edge as is possible, use is made of auxiliary side links composed of a single strand of wire. rllhese side or auxiliary links 23 serve the two-fold function of the main links and the coupling links. For this purpose the limb section 24 of each one of the left-hand longitudinal links 23 (viewing llig. 1) cooperates with the limb section 11 of each one of the longitudinal row of main links 9, and the limb section 24 of each one of the right-hand longitudinal row of links 23 cooperates with the limb section 12 of each one of the adjacent longitudinal row of m'ain links. The loop portion 25 of the auxiliary links 23 performs the function of the coupling links in that the hook 26 of each link 23 is received in the nearer pocket 14 of the adjacent main link, and the hook end 27 of each link 23 is received' in the loop 25 of the preceding link 23, in which loop is also received the loop 17 of the limb 11 or 12 of the adjacent main link.

What I claim as my invention and desire to secure by Letters-Patent, is:

l. A wirefabric for beds and the like comprising a series of lateral rows of longitudinally extending main links, each main link consisting of a pair of parallel limbs connected at one end by a curved transverse member which forms a pocket with each limb, the free ends of the limbs being hookshaped and diverging from each other, a series of lateral rows of coupling links, each coupling link having its free ends hookshaped for engagement in the nearervpockets ot two adjacent main links, the middle portion of each coupling link being formed as a loop for the reception of the convergent hooks of adjacent main links, and a series of single strand auxiliary links arranged at cach side of the fabric, each auxiliary link being connected with an adjacent main link and having a loop adapted to receive a hook of an adjacent main link and a hook of the next succeeding auxiliary link.

2. A wire fabric for beds and the like comprising a series of lateral rows of main links, a series of lateral rows of coupling links, and two longitudinal series of auxiliary links, all of said links interengaging and cooperating to constitute the fabric, cach main link consisting of two substantially parallel limbs connected by a curved transverse member forming a pocket with each limb, the free ends of the limbs being odset to diverge from each other and provided with hooks, each coupling link consisting oi aV loop and two hooks, the hooks of the coupling link' being adapted to be received in the nearer pockets of two adjacent main links and the loop portion of each coupling link being adapted to receive the two nearer hooks of succeeding adjacent main links, and each auxiliary link consisting of a single strand limb having a hook at one end and an offset loop and a hook at the other end, the loop being adapted to receive a hook of an adjacent main link and a hook of the next succeeding auxiliary link, and the hook at the looped portion of the auxiliary link being adapted to be received in the tree pocket of an adjacent -main link.

ln testimony whereof l hereunto aliix my signature.
